Washing machine

Abstract

A laundry machine constructed to discharge liquid from rotating nozzles into a basket, impacting and agitating fabrics and clothes within basket. Nozzles are located under cover door and above basket. Pump recirculates the liquid and the reaction force of the liquid flowing through the nozzles rotates nozzles. Spin rotation of the basket extracts liquid from fabrics and clothes.

I claim: 
     
       1. A washing machine apparatus comprising: (a) a tub,   (b) a basket containing fabrics to be cleaned, said basket being disposed within said tub for draining a liquid from said basket into said tub,   (c) a motor,   (d) a pumping means connected to one end of said motor for recirculating said liquid between said basket and said tub, for draining said tub of said liquid upon reversing rotation of said pumping means,   (e) a recirculating liquid conduit having two directly opposite ends and a third end, one of the said two directly opposite ends connected to the said pumping means for transferring said liquid from said pumping means to said recirculating liquid conduit,   (f) two conduit swivels having each a pivoting end and a non pivoting end, said non pivoting end of one of said two conduit swivels connected to other end of said two directly opposite ends of said recirculating liquid conduit for transfer of said liquid through said recirculating liquid conduit to said non pivoting end of one of said two conduit swivels,   (g) a conduit having two opposite ends and a third end, said two opposite ends of said conduit connected to said pivoting ends of said two conduit swivels for support of said conduit, for transfer of said liquid through one of said two conduit swivels, for pivoting said conduit from a predetermined horizontal position of said conduit to a predetermined vertical position of said conduit for placement and removal of said fabrics from said basket,   (h) a cover mounted on said conduit for supporting said conduit in a predetermined horizontal position when said cover is in a closed predetermined horizontal position,   (i) a nozzle swivel having a nonrotating end, said nonrotating end connected to said third end of said conduit for support of said nozzle swivel and for transferring said liquid through said conduit to said nonrotating end of said nozzle swivel,   (j) a rotating end of said nozzle swivel connected to said nonrotating end of said nozzle swivel for rotation of said rotating end of said nozzle swivel and for transfer of said liquid through said nonrotating end to said rotating end of said nozzle swivel,   (k) a plurality of nozzles connected to said rotating end of said nozzle swivel for transfer of said liquid through said rotating end of said nozzle swivel to said plurality of nozzles, for rotation of said plurality of nozzles, for discharge of said liquid from said plurality of nozzles in circular paths into said basket, said plurality of nozzles mounted above and outside of said basket,   (l) two check valves having inlet ends connected to said tub for draining said liquid from said tub and for preventing said liquid from entering said tub through said two check valves,   (m) an outlet end of one of said two check valves connected to said third end of said recirculating liquid conduit for transferring said liquid from said tub to said pumping means upon reverse operation of said pumping means,   (n) a drain liquid conduit having two opposite ends and a third end, one of said two opposite ends connected to said pumping means for tranferring said liquid in said drain liquid conduit to said pumping means,   (o) an outlet end of other one of said two check valves connected to other one of said two opposite ends of said drain liquid conduit, for tranferring said liquid through said outlet end of other one of said two check valves into said drain liquid conduit,   (p) a third end of said drain liquid conduit having a predetermined vertical height above said two check valves, for preventing gravity draining of said liquid from said tub into atmosphere, for discharging said liquid upon reverse operation of said pumping means,   (q) an over running clutch means connected to other end of said motor for transmitting rotational energy when said motor operates in reverse rotation,   (r) a belt connected to said over running clutch means for transmitting rotational energy from said over running clutch to said belt,   (s) a pulley connected to said belt for transmitting rotational energy from said belt to said pulley,   (t) a shaft connected at one end to said pulley for transmitting rotational energy from said pulley to said shaft, and   (u) other end of said shaft connected to said basket for transmitting rotation of said shaft to said basket for spin drying of said fabrics in said basket.   
     
     
       2. A washing machine apparatus as recited in claim 1 in which, (a) bores of said plurality of nozzles having a predetermined circular shape for minimizing pressure losses in said liquid flowing through said bores of said plurality of nozzles,   (b) cross-sectional areas of said bores of said plurality of nozzles having a predetermined same size of said cross-sectional areas throughout said bores of said plurality of nozzles for discharging solid and full streams of said liquid into said basket,   (c) ends of said plurality of nozzles having a predetermined curvature for discharging said liquid into said basket, for changing the direction of flow of said liquid in said ends and creating a rotating torque in said plurality of nozzles for rotating said plurality of nozzles, and   (d) lengths of said plurality of nozzles having each a predetermined different size for discharging said liquid onto different areas in said basket.
